Decoherence is the bane of quantum technologies. In coherent systems, the phase of the wave functions representing the quantum states of particles in the system have definite relations between each other. This allows quantum devices to operate in a meaningful way that differs from classical devices. However, interacting with the world around us rapidly leads to decoherence, which makes it harder to exploit quantum effects for enhancing computation efficiency or communication security. Research has shown that quantum systems with impressively long coherence times are possible in diamond, but diamond is far from the favorite for manufacturers. Now, researchers at the University of Science and Technology in Hefei and Wuhan University in China have demonstrated SiC can boast some of the quantum merits of diamond with the additional advantage of optical control at the wavelengths used by the telecommunications industry.

In his latest line of research, Cun-Zheng Ning, a professor of electrical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University, and his peers explored the intricate balance of physics that governs how electrons, holes, excitons and trions coexist and mutually convert into each other to produce optical gain. Their results, led by Tsinghua University Associate Professor Hao Sun, were recently published in the Nature publication Light: Science & Applications.

The huge detectors providing a window to the world's tiniest particles are set for a $153 million upgrade, and a team of Purdue University scientists will play a key role—continuing the university's decades-long legacy with the historic experiments at the European Organization for Nuclear Research, or CERN.

Astronomers from South Korea and China have performed a deep X-ray spectral imaging of a bow-shock pulsar wind nebula (PWN) associated with a nearby pulsar designated PSR B1929+10. The new study, published April 29 on arXiv.org, presents the deepest investigation of the system, disclosing important information about the emission from this PWN.

China plans to send four crewed space missions and the same number of cargo craft to complete work on its permanent space station within about two years, officials said after the launch of a newly designed spacecraft aboard the latest heavy-lift rocket.

A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth. The black hole is closer to our Solar System than any other found to date and forms part of a triple system that can be seen with the naked eye. The team found evidence for the invisible object by tracking its two companion stars using the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile. They say this system could just be the tip of the iceberg, as many more similar black holes could be found in the future.

Researchers have spent decades looking for evidence of ancient water on Mars. As technology has progressed, more evidence has come to light that rivers, lakes and even oceans were once abundant on the red planet.

Our sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish. This does not mean the sun doesn't have an active side. We have observed massive solar flares, such as the 1859 Carrington event, which produced northern lights as far south as the Caribbean, and drove electrical currents in telegraph lines. If such a flare occurred in Earth's direction today, it would devastate our electrical infrastructure. But fortunately for us, the sun is mostly calm—unusually calm when compared to other stars.

Billions of years ago, the Martian surface could have supported microbial life as we know it. But did such life ever actually exist there? NASA and its Mars 2020 mission hope to find out with the Perseverance rover, which launches to the Red Planet this summer.

The US Air Force said Wednesday it would be sending its high-tech X-37B space drone back into orbit this month—the sixth trip for the reusable vehicle that maneuvers around the Earth on secretive missions.

Researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea have recently introduced a method to produce thin and patterned transition metal ditelluride films to be integrated in 2-D metal semiconductors. Their synthesis technique, presented in a paper published in Nature Electronics, could mitigate the challenges associated with the high contact resistance of existing electronics based on 2-D materials.

Open source graph machine learning library StellarGraph has today launched a series of new algorithms for network graph analysis to help discover patterns in data, work with larger data sets and speed up performance while reducing memory usage.

The quest to find viable alternatives to fossil fuels in energy production has experienced a recent revolution as scientists search for materials that do not require precious metals to produce active and stable reactions.

Everybody loves to hate taxes. And unless you are lucky enough to live in one of a small handful of countries with no income tax—Bermuda, Monaco or the United Arab Emirates, for instance—you likely dread Tax Day when you dig deep into your pockets and send a chunk of your hard-earned cash to government coffers.

Dr. Tracy Xu, lecturer in hospitality at the University of Surrey's School of Hospitality and Tourism Management, has published a paper in the International Journal of Contemporary Hospitality Management derived from interviews with 19 hotel HR experts to identify the key trends and major challenges that will emerge in the next 10 years and how leaders should deal with the challenges brought about by service robot technologies.

FOSH is rapidly gaining momentum as part of a global "open design movement," whereby the free release of information on customized research hardware, such as design, schematics and bill of materials are easily accessible anywhere with an internet connection.

Facebook on Wednesday announced the first members of its independent "supreme court" empowered to make binding decisions about what content should be allowed or removed at the social network and Instagram.

Modern technology affects different workers in different ways. In some white-collar jobs—designer, engineer—people become more productive with sophisticated software at their side. In other cases, forms of automation, from robots to phone-answering systems, have simply replaced factory workers, receptionists, and many other kinds of employees.

Here is a list of the members of the Facebook "supreme court" announced Wednesday, who will consider difficult decisions on what content to allow or remove from the world's largest social media platform.

Some 61 percent fewer new cars were registered on German roads in April 2020 than a year ago, official data showed Wednesday, as Europe's automobile powerhouse matched its neighbours' plunging sales for the industry.

Q: During Zoom video calls, my screen image follows my actual movements very slowly. If I move my head or speak, there's sometimes a delay of two seconds or more before it happens on my screen. (This didn't happen during a Microsoft Teams video call.) Other people in the Zoom meeting say they don't have the same problem. I've updated Zoom and my Windows 10 PC, but nothing helps. What's wrong?

To prove that tastes moves in cycles, tactical turn-based strategy games have seen a resurgence again. Sparked by the success of "XCOM: Enemy Unknown," more titles have tried to find their niche in the category.

The United States formally notified the World Trade Organization on Wednesday of the elimination of a state tax break for aerospace giant Boeing to avoid retaliation by the European Union.
